Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol. The periodic table’s arrangement also allows scientists to discern trends in element properties, including electronegativity, ionization energy, and atomic radius.
Why is it called the periodic?
Why is the periodic table called the periodic table? It is called the periodic table because of the way the elements are arranged. You’ll notice they’re in rows and columns. The horizontal rows (which go from left to right) are called ‘periods’ and the vertical columns (going from up to down) are called ‘groups’.

Who made periodic law?
Dmitri Mendeleev
The periodic law was developed independently by Dmitri Mendeleev and Lothar Meyer in 1869. Mendeleev created the first periodic table and was shortly followed by Meyer. They both arranged the elements by their mass and proposed that certain properties periodically reoccur.
Who proposed periodic law?
Who gave the modern periodic law? In 1869, Dmitri Mendeleev and Lothar Meyer established the periodic law independently. The first periodic table was developed by Mendeleev and soon followed by Meyer. Each grouped the elements by their mass and proposed regularly reoccurring those properties.
